Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants are patients who will be undergoing elective hip and knee replacements and lumbar decompression.
The intervention is a motivational script developed based on previous Challenge and Threat state studies. It will be delivered by a trained member of the study team via phone to the participant undergoing surgery. The intervention will be delivered once two days prior to the scheduled date of operation. The participants will be expected to receive the phone call in their own home.
Participants from the same group will receive the same scripted intervention, i.e. those in the intervention group will receive the Intervention Script and those in the control group will receive the Control script (a scripted phone call without the intervention).
The initial script for both phone calls are the same: participants will be asked questions about their feelings towards the operation and post-operative recovery and then informed that they will meet a member of the research team and answer some questionnaires on the day of surgery. The script for the control group terminates here.
For the intervention group, the script continues and the intervention is delivered. Topics covered includes:
- supports available during hospital stay and post-discharge
- what participants can expect post-operatively
The phone calls are anticipated to last 5-10 minutes depending on which script the patient receives.
The intervention will be delivered by a member of the research team; phone logs will be audited to monitor the delivery of the intervention.

Behaviour
Comparator / control treatment
The control group/comparator for this study will be patients undergoing elective hip and knee replacements and lumbar decompression who have not received the intervention. Both groups will be receiving the the standard care; however the only difference is the intervention group will receive the intervention prior to their planned procedure date. The standard care involves: routine pre-, intra- and post-anaesthetic and surgical cares, then routine cares on the ward. Routine care on the wards involves multidisciplinary team approach (physiotherapist, occupational therapist, nursing etc.) for rehabilitation and discharge planning.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is not concealed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients who have consented to participate in the study will be randomised into the intervention group or the control group using block randomisation with block sizes of eight.
The block randomisation will be computer generated using a randomisation software. Patients and the surgeon will be blinded to the allocation.
Masking / blinding
